Does decreasing smoking frequency decrease mortality

Cigarette smoking is one of the leading causes of preventable deaths worldwide. Despite the well-established link between smoking and mortality, many smokers struggle to quit entirely. Some smokers may attempt to reduce their smoking frequency as a way to decrease their health risks. But does decreasing smoking frequency actually decrease mortality? Let's take a closer look.


First, it's important to understand the health risks associated with smoking. Smoking is a major cause of lung cancer, chronic obstructive pulmonary disease (COPD), and heart disease. It can also increase the risk of stroke, respiratory infections, and several other types of cancer.


The risks associated with smoking are dose-dependent, meaning that the more cigarettes a person smokes, the greater their risk of health problems. This has led some smokers to believe that reducing their smoking frequency will reduce their health risks.


However, research suggests that this may not be the case. A study published in the Journal of the American Medical Association (JAMA) in 2015 found that reducing smoking frequency did not lead to a significant decrease in mortality risk. The study followed more than 15,000 smokers over a period of 16 years and found that those who reduced their smoking frequency by half or more still had a similar risk of mortality as those who continued to smoke regularly.


Another study published in the American Journal of Preventive Medicine in 2019 found similar results. The study followed more than 7,000 smokers over a period of 16 years and found that reducing smoking frequency was not associated with a significant decrease in all-cause mortality or mortality from specific causes like cancer or heart disease.


These studies suggest that reducing smoking frequency may not be an effective strategy for reducing health risks associated with smoking. But why is this the case? One possible explanation is that smoking even a small amount of cigarettes can have a significant impact on health. According to the Centers for Disease Control and Prevention (CDC), even smoking as few as one to four cigarettes per day can increase the risk of heart disease and lung cancer.


Another explanation is that reducing smoking frequency may not be sustainable for many smokers. Nicotine is highly addictive, and many smokers may find it difficult to maintain a lower smoking frequency over the long term. This could lead to a pattern of quitting and relapsing, which could be more harmful than quitting altogether.


So if reducing smoking frequency isn't an effective strategy, what can smokers do to reduce their health risks? The most effective strategy is to quit smoking entirely. While quitting smoking can be difficult, it is the best way to reduce the risk of health problems associated with smoking.


There are many resources available to help smokers quit, including nicotine replacement therapy (NRT), prescription medications like bupropion and varenicline, and behavioral therapies like counseling and support groups. Many smokers may find that a combination of these strategies is most effective.

Quitting smoking can have immediate and long-term health benefits. Within just a few weeks of quitting, smokers may experience improvements in lung function, circulation, and immune function. Over the long term, quitting smoking can significantly reduce the risk of lung cancer, COPD, heart disease, and other health problems.



In addition to quitting smoking, there are several other steps that smokers can take to reduce their health risks. These include: 


  • Avoiding exposure to secondhand smoke: Secondhand smoke can also increase the risk of health problems like lung cancer, COPD, and heart disease. Smokers should avoid smoking around others and should avoid exposure to other people's smoke. 

  • Eating a healthy diet: A diet that is high in fruits, vegetables, whole grains, and lean proteins can help reduce the risk of several health problems. 
  • Exercising regularly: Regular exercise can improve cardiovascular health, lung function, and overall fitness. 
  • Getting regular health screenings
